CM1000 Xfinity issues
I am quite frustrated at this point. I had a CM600 modem to support Comcast's Extreme 150 service. I've had it for a few years and was consistently getting 160 to 170mbps speed from it. About thre...
Well it is finally fixed. The tech showed up today and I showed him the two frequencies that were having the problem. He checked outside, and then at the tap. He came into the house and said he needed to call a bucket truck in to fix it. I got a recorded call from Comcast that they were working to fix the issue. I got a second call an hour later that the issue was fixed. I ran a speed test and got a consistent 160mbps (yay!). I used the reset button on the modem and let it re-provision. All the signal/noise and power levels were good and there were no uncorrectable codewords. They didn't tell me what they fixed, but at long last, it is fixed.
Are you doing the speed tests directly from the modem or do you have a router in between?

Yes DarrenM. It was the first thing I did. The same issue was happening on my CM300 and they said it was the modem so I bought the CM1000 brand new from BestBuy. Comcast even trenched a new thicker cable from the street junction to the box in the house, and replaced the split line that the modem was connected to to a direct line from the modem to the box. I had an open cased with them through @comcastcares on Twitter and I pinged them today demanding to be connected to L3 support. He said he saw noise in the signal and wanted to send a tech. I told him that's what you said the last time and they came out and replaced the cable. I've been in the software and hardware business for 40 years and I can tell when someone is minimally trained and just taking shots in the dark. Let me know if you need any other information.
